SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 348,342, dated August31, 1886.

Application filed May 24, 1886. Serial No. 203,103.

To all whom t may concern:

Beit known that I, HOWARD POWELL, a citizen of the United States,residing at Chicago, in the county of Cook and State otIllinois, haveinvented a certain new and uscful Improvement in Vindow-Sash Fasteners,ofwhich the following is a specification.

The object of my invention is to provide windows with means whereby theymay be Securely fastened and prevented from rattling, both when partlyand completely closed.

The invention consists in the combination of two pieces of brass orother suitable metal, so constructed that when placed in a certainposition with reference to each other and the sash and frame they will,when the window is completely closed, automatically fasten it, and thatwhen the window is partly openedto such an extent as to bring saidpieces of metal into a certain juxtaposition-they will automaticallysecure the sash against further opening, except from the inside. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure l is a window frame and sash with myinvention attached thereto; Fig. 2, a vertical section of a frame andsash with my invention attached, Figs. 3 and 4, the front and sideviews, respectively, of one of said pieces of metal, and Figs. 5 and6,frontviews ofthe other ofsaid pieces of metal.

Similar letters refer to similar parts throughout the several views.

E represents the window-frame; F, the sash, and ab and c the two piecesof metal, which last two, taken together, constitute. my invention.

ab is a flat metallic spring, which is screwed to the windowsash at oneend, b, with the end a sprung out from the sash, so that when sprung outit catches tightly in the piece c, which is a piece of brass or othersuitable metal set in and screwed to the side of the windowframe, andprovided with a projecting corner or ledge, against which and into whichthe flat piece of metal ab, when sprung out, catches. Then the spring abis pressed against the windowsash, the end a is released from the ledge,and the window may then be opened, or, if already partly opened, may beopened farther.

(No model.)

Itis to be understood that the two pieces of metal ab and c are of asize and weight varying in proportion to the size and weight of thesash, and that they may be screwed to the sash and frame, respectively,at any point which may be requisite, taking into consideration the sizeof the window, to secure the above results.

The peculiar advantage and utility of my invention are, that by its use,as indicated above, upon window sashes and frames, the sash is preventedfrom rattling, facility is obtained :in opening the window from theinside, perfeet security is obtained against the window being openedfrom the o utside when entirely closed, and especially that the twometallic pieces ab and c may be screwed into the sash and frame,respectively, at such positions that though the window may be partlyopened it will still be impossible to open it from the outside beyondthe point at which ab and c (said metallic pieces) hold it when the endyof the piece ab rests against the ledge.

I am aware that it is not new to provide windows with catches andsprings fastened to frame and sash, respectively, and in combinationholding the sash in the frame; but these do not embody my invention, theessential novelty of which is found in the fact that the shape of thespring and catch is such as to make them fit easily and yet perfectlyinto and against each other, and yet possess the quality of the greatestpossible strength with the greatest economy of metallic material.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

A metallic spring, ab, one end of which, c, is free, and the other endofwhich, b, is secured to the side of a sash, and a metallic catch, c,secured to the adjacent side of a frame and provided with a raisedledge, in their combination holding the sash firmly at any desired pointin the frame, substantially as set forth.

HOWARD POWELL.
